S U LKY-PLQW.

.SPEGIFICA'IION' forming part of Letters Patent No. 482,734, datedSeptember 20, 1892. Application filed May 9, 1892. fierial No. 432,371.(No model.)

To all whom it may concern.-

Be it known that'I, ll/IICHAEL GLYNN, a citizen of the United States,residing at Otter bein, in the county of Benton and State of Indiana,have invented a certain new and useful Improvement in Sulky-Plows, ofwhich the following is a specification.

My invention relates to the improvement of sulky-plows, and hasparticular relation to the construction and arrangement of an improvedsteering-gear for said class of plows.

The objects of my invention are to provide an improved form of steeringfor'plows of such superior construction and arrangement of parts as tofacilitate the directing of the plow in the proper course, to obviatethe necessity of employing a tongue and the usual tongue parts, and toproduce other improvements, which will be more specifically pointed outhereinafter.

These objects I accomplish in the manner illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of a plow having myimprovements thereon. Fig. 2 is a plan view. Fig. 3 is a front end view.Fig. e is an enlarged sectional View on line 00 a: of Fig. 3, and Fig. 5is an enlarged transverse section on line y y of Fig. 3.

Similarletters refer to similar parts throughout the several views.

a represents a plow-beam, and b represents the large side wheel thereof,which is mounted on the outer end of a crank-shaft b, the inner end ofwhich has a bearing in asuitable frame 11 which projects laterally fromthe beam (1.

b represents the plowshare, which depends from the rear portion of thebeam at in the usual manner.

From the forward portion of the beam proj ects laterally an arm I), theinner end of which is rigidly connected with said beam. The outer endportion of this arm 19 has formed therein a vertical passage or opening,within which is pivotally supported a tubular bushing-thimble b theenlarged head of which bears upon the upper side of said arm I) and thecentral opening or hollow of which is square in crosssection.

0 represents a rod or standard, which is square or angular incross-section and which passes, as shown, vertically through the thimbleZr". Upon the rounded lower and outwardly-bent end of the rod 0 ismounted a front guide-wheel c, which is adapted to bear upon the ground.At a point above the arm b the rod 0 has secured thereto the outer endof an inwardly-extending lever-arm 0 The outer end of this arm 0 isfurther connected with the rod 0 by a suitable brace-arm 0 which extendsfrom said arm a to the upper end portion of said rod.

Mounted upon the upper end portion of the rod 0, beneath the outer endof the brace-arm c, is ablock c, with the outer side of which isconnected a semicircular and rearwardly-extending rack-plate 0 To theouter side of this rack-plate c or block 0 is pivotally connected 2].rearwardly-extending lever-ar1n c, which is provided with a suitablepivoted pawl c on its inner side, which is adapted to be brought intoengagement with the teeth of the rack 0 The forward end of the lever-armc has pivotally connected therewith the upper end of adownwardly-extending arm a the lower end of which is fulcrumed to a lugc, which projects from the forward side of the arm b Rising from apivotal connection with one side of the beam a, at a point near thecenter of the length thereof, is a lever-arm d, which, as shown at d, isprovided with a pawl, which is adapted to be brought into engagementwith the upwardly-projecting teeth of a semicircular rack-plate 02 whichrises from the beam at.

The lever-arm d has pivoted thereto the rear end of a connecting bar orrod 6, the forward end of which is jointedly connected with the innerend portion of the arm 0 Rising from the framework adjacent to the beamat is a seat f. To the outer or forward end of the beam a, whichterminates a short distance in front of the arm 6 is adapted to beconnected, as shown, a whiffietree-clevis g. Depending from the rear endof the beam on is a suitable form of swivel-arm g, which carries therear ground or caster wheel 9 In operating my improved steering-gear itis evident that the position of the forward wheel 0 maybe adjusted tochange the direction of travel by raising the pawl (1 out of engagementwith the teeth of the rack 11 and forcing the lever d forward orbackward, as

1 seen that a simple and reliable means is afforded of guiding orchanging the direction of the plow without the use of a tongue.

It is evident that the plow-beam may be thrown upward or downward, asdesired, by

. producing a disengagement of the pawl c" with the teeth of the rack cand moving the lever c upward or downward to the desired position. Thismovement of said lever a will result through the connection of the arm aand arm 19 and the connection of the latter with the beam in the desiredmovement of said beam.

The construction and arrangement of parts herein described and shown notonly afford a simple and reliable steeringear for plows of this class,but obviates the necessity of employing a tongue, and thus greatlylessens the expense of construction. It will also be seen that byomitting the tongue from the construction of the plow the furrowproduced by the share I) may be continued to within close proximity tothe fence or other obstacle and still permit of the horses being turned.It will also be observed that the construction of my improvedsteering-gear is such as to admit of its attachment to many of theordinary forms of sulky-plows.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

1. In a plow, the combination, with the beam, side wheel 1), andcaster-wheel 9 of a rod 0, supported in the forward portion of theframework, a guide-wheel on said rod, a lever d, and a connectingmechanism between said lever d and rod 0, by means of which rotarymotion is imparted to said rod through the motion of said lever,substantially as and for the purpose specified.

2. In aplow, the combination, with the plowbeam, its share andsupporting wheels, and a lever d, rising from the framework, of beamarm1), rod 0, journaled thereto and carrying wheel 0, arm 0 projecting fromsaid rod 0, and a connecting-piece 6 between said arm 0 and lever d,substantially as and for the purpose specified.

3. In a plow, the combination,with the beam, share, and framework,supporting-wheels therefor, and a lever d, fulcrumed to said frame, ofan arm 19, projecting, as described, from the beam, wheel-carrying rod0, journaled in 'said arm, rack c on the upper end of said rod 0,lever-arm c fulcrumed to said rack, arm connecting said lever-arm andarm 5 and connecting-piece 6 between said arm 0 and lever d,substantially as and for the purpose specified.
